ZOOLOGICAL RESEARCH Tube-nosed variations–a new species of the genus Murina (Chiroptera: Vespertilionidae) from China DEAR EDITOR, M. shuipuensis from Guangxi and Guizhou (Eger & Lim, 2011), and M. fanjingshanensis (He et al., 2015), M. During a survey in 2014, several tube-nosed bats rongjiangensis (Chen et al., 2017), and M. liboensis (Zeng et (Vespertilionidae: Murininae: Murina) were collected in al., 2018) from Guizhou. Thus, at least 19 species belonging Sichuan Province. Based on morphological characters, these to the genus Murina are currently known from China (Chen et bats did not match any species previously recorded from al., 2017; Eger & Lim, 2011; He et al., 2015; Jiang et al., 2015; China. Morphometric analyses and phylogenetic inference based on mitochondrial and nuclear gene sequences Kuo et al., 2009; Liu & Wu, 2019; Zeng et al., 2018). indicated that they represented a new species, named here as In 2014, several small-sized and impressively colored Murina jinchui sp. nov. Although the new species is presently Murina individuals were collected during field surveys in known only from Wolong National Nature Reserve, it is Sichuan Province (all field surveys and sample collection unlikely to be a rare species in the area based on our capture protocols complied with the current laws of Sichuan Province). frequencies. Morphological and molecular biological examinations revealed Characterized by tubular nostrils and relatively well- them to be distinct from all other recognized Murina taxa; developed anterior upper premolars, the Old World subfamily therefore, they are described herein as a new species. of vespertilionid bats, Murininae Miller, 1907, is rich in cryptic For morphometric analysis, we examined 224 specimens of species. Typically, these species are rare in collections, which Murina deposited in 12 collections (see list of specimens in have contributed to our poor understanding of their diversity Supplementary Material (Appendix I)). Six external and distribution. Simmons (2005) listed 17 species within the measurements (to the nearest 0.1 mm), body mass (to the subfamily, but several new species have been described since nearest 0.1 g), and 16 craniodental measurements (to the due to an increase in survey efforts, improved capture nearest 0.01 mm) were recorded by the same author. methods, re-evaluation of taxonomically informative Definitions and details of measurements are listed in the Table characters, and species delimitations using DNA barcoding 1 and Supplementary Material (Methods). (Csorba et al., 2011; Eger & Lim, 2011; Francis et al., 2010). We performed principal component analysis (PCA) and As such, 39 species are currently recognized based on discriminant analysis of principal components (DAPC) taxonomic revisions and new species descriptions (Chen et (Jombart, 2008; Jombart et al., 2010) for species al., 2017; Csorba et al., 2007, 2011 Eger & Lim, 2011; Francis discrimination based on external and craniodental & Eger, 2012; Furey et al., 2009; He et al., 2015; Kruskop & measurements. For both PCA and DAPC, the sexes were Eger, 2008; Kuo et al., 2009; Maeda & Matsumura, 1998; analysed separately because sexual dimorphism is noted in Ruedi et al., 2012; Soisook et al., 2013a, 2013b Son et al., 2015; Zeng et al., 2018).
